Covid sucks, but this is great yo use for relief from the frustrations caused by the recent lockdowns.Just grab the ball and smash it into the floor… it can handle it really well.

Open the box at home and the ball was deformed. A little throwing around doesn’t bring the ball (back?) to it’s intended shape. It remains a deformed lump of hardness. Unusable.

This slam ball goes into a flat rock shape when used. Apparently it needs air added but there are no instructions included. I emailed asking for instructions and didn’t hear back. Disappointing & hard to use.

Got the ball out if the box and it was fully deflated, i took it back into rebel to have them pump it up and the lady said thats how it was meant to be. I did a ball slam and it literally just flattened liked a pancake to the ground, she reckons its not meant to bounce back up.... so i exchanged it for the 4.5kg instead, which was much better and inflated properly and definetely had a small bounce like a slam ball should.
The ball does it’s job but it loses its shape easily. I have used other slam balls that maintain their sphere. Unfortunately this one becomes flattened and makes it awkward to use.
Great for working my back muscles whilst gyms are closed.It’s easy to use but strongly advise using gym fingerless gloves to protect your hands and to protect your hands
It's a tough thing and I like it. My only remarks is with every slam it flattens too much to the ground making it hard to take back up unlike other slamballs I've trained with. Also, the surface is just a bit too smooth making grip a little tricky - not a big issue though. Overall, I'm happy with it and it's staying with me for a long time. Thank you
Great quality, as description states. Only thing I didn't realise from when buying online is that the slam ball changes shape when slammed on ground - doesn't always stay as a sphere. Not detrimental but not what I was expecting.
I have used a few slam balls over the years, but this one is the worst. On the first slam it changed shape like a bad football or really flat which made it hard to pick up and the more I used it the softer it became making it even harder to pick up. Definitely taking it back for a refund. Some of Celsius gym equipment is absolute rubbish.
I bought this yesterday and it is very rough on the hands - I have skinned fingers after one use … no instructions provided so didn’t realise the ball needed additional air (it looked already inflated) before use … felt like misshapen concrete and formed odd ellipses after each slam. Lots of sand spilling from the hole today. Returning tomorrow!
